Ratings and reviews

worked perfectly and saved my project! I don't have a computer right now so I needed to flash my adafruit reverse TFT feather and update the bootloader without a computer the first app I downloaded didn't work at all even though it said that it did it confirmed that it was uploaded properly and then wasn't this worked perfectly! And quickly and honestly couldn't be better

Great app! It worked perfectly for me. I flashed all four binary files. Initially, the process failed, but after putting my ESP32 into download mode, everything worked as expected.

Very good app to flash the ESP Modules / Chip. Clean interface. Works very well.
